1ED3121MU12H

Overview

5.5 A, 5.7 kV (rms) single-channel isolated gate driver with separate output, UL 1577 certified, 10.5 V UVLO

EiceDRIVER™ Compact single-channel isolated gate driver with 5.5 A typical sinking and sourcing peak output current in DSO-8 wide-body package with large creepage distance (>8 mm) for IGBTs, MOSFETs and SiC MOSFETs.

1ED3121MU12H belongs to the EiceDRIVER™ Compact 1ED31xx family (X3 compact family). 1ED3121 offers separate sink and source output, accurate and stable timing, active shutdown to ensure a safe IGBT off-state in case the output chip is not connected to the power, short-circuit clamping to limit the gate voltage during short circuit. The driver can operate over a wide supply voltage range, either unipolar or bipolar.
